Dana Wireless Setup Guide 33

APPENDIX A Wi-Fi Terms and

Dana Interface

Refer to the table below for deﬁnitions of common Wi-Fi terms.

TABLE 1. Wi-Fi Terms

Access Point A wireless LAN transceiver or “base station” that

provides a wireless connection to a Wi-Fi network

for one or many wireless devices.

DHCP

(Dynamic

Host

Conﬁgura-

tion

Protocol)

A utility that enables a server to dynamically assign

IP addresses from a predeﬁned list and limit their

time of use so that they can be reassigned. Without

DHCP, an IT Manager would have to manually

enter in all the IP addresses of all the computers on

the network. When DHCP is used, whenever a

computer logs onto the network, it automatically

gets an IP address assigned to it.

Encryption

(WEP -

Wired

Equivalency

Protocol)

Basic wireless security provided by Wi-Fi to protect

Wi-Fi networks from unauthorized access. WEP is

available in 40-bit (also called 64-bit), or in 108-bit

(also called 128-bit) encryption modes. Since 108-bit

encryption provides a longer algorithm that takes

longer to decode, it usually provides better security

than 40-bit encryption.

Encryption

Key

An alphanumeric series that enables data to be

encrypted and then decrypted so it can be safely

shared among members of a network. WEP uses an

encryption key that automatically encrypts outgoing

wireless data. On the receiving side, the same

encryption key enables the computer to automati-

cally decrypt the information so it can be read.
